In this paper, we present a novel approach for the change discovery in the ontology-based knowledge management systems. It extends our previous work in the ontology evolution by taking into account the usage of the ontology in the knowledge management system. The approach is mainly based on the analysis of the user's interaction with the system in providing annotations for knowledge resources, as well as in the process of accessing the knowledge by querying the knowledge repository. We defined several assessment criteria to estimate the quality of annotations and the user's needs from the point of view of the knowledge management. These criteria result in the recommendations for the continual system improvement. Two evaluation studies illustrate the benefits of our approach.
